lib: Support vector extension

2020-04-17T04:00:17Z

Enable vector context in mstatus by updating the corresponding bits in mstatus if vector extension is supported by the hart. Signed-off-by: Atish Patra Reviewed-by: Bin Meng Reviewed-by: Anup Patel

lib: Extend trap redirection for hypervisor v0.5 spec

2019-12-16T09:18:26Z

The hypervisor v0.5 spec introduces two new CSRs for both M-mode and HS-mode which need to be considered when redirecting traps hence this patch. Signed-off-by: Anup Patel

include: Add guest external interrupt related defines

2019-12-16T09:18:12Z

With RISC-V H-extension v0.5 draft, we have special support for guest external interrupts so this patch adds related defines which were missed-out previously. Signed-off-by: Anup Patel Reviewed-by: Alistair Francis

include: Use _UL() and _ULL() for defines in riscv_encoding.h

2019-11-06T05:07:24Z

The riscv_encoding.h is shared with assembly sources so we use _UL() and _ULL() for register fields related defines. Signed-off-by: Anup Patel Reviewed-by: Atish Patra

include: Sync-up encoding with priv v1.12-draft and hypervisor v0.5-draft

2019-11-06T05:05:41Z

This patch sync-up encoding header with the latest privilege specifications draft v1.12 and hypervisor specifications draft v0.5. The MSTATUS.MTL and HSTATUS.STL bits are not present anymore and will be removed by another patch series for hypervisor v0.5-draft. Signed-off-by: Anup Patel Reviewed-by: Atish Patra

lib: Emulate HTIMEDELTA CSR for platforms not having TIME CSR

2019-09-30T10:06:14Z

For platforms not having TIME CSR, we trap-n-emulate TIME CSR read/write in OpenSBI. Same rationale applies to HTIMEDELTA CSR as well so we trap-n-emulate HTIMEDELTA CSR for platforms not having TIME CSR. Signed-off-by: Anup Patel

lib: Redirect WFI trapped from VS/VU mode to HS-mode

2019-09-30T10:02:00Z

The WFI will trap as illegal instruction trap when executed in VS/VU mode so we just forward/redirect it to HS-mode so that hypervisor can deal with it appropriately. Signed-off-by: Anup Patel

lib: Extend sbi_trap_redirect() for hypervisor extension

2019-09-30T09:59:37Z

When hypervisor extension is available, we can get traps from VS/VU modes. We should be able to force redirect some of these traps to HS-mode. In other words, we should be able forward traps from VS/VU mode to HS-mode using sbi_trap_redirect() hence this patch.

lib: Extend sbi_hart_switch_mode() to support hypervisor extension

2019-09-30T09:48:06Z

This patch extends sbi_hart_switch_mode() to support entering VS/VU modes when hypervisor extension is available. Signed-off-by: Anup Patel

all: Annotate some tables to have clang-format leave them alone

2019-04-24T04:19:46Z

One of the shortcomings of clang-format is that it doesn't allow for aligned define tables, which is used for a number of constants. Add annotation to disable the automatic formatting where needed. Signed-off-by: Olof Johansson
